Prevent end users from manually selecting a label used for auto classification
Create a label for automatic classification, add the label to a label policy, but prevent end users from manually selecting that label or hide the label from end user view.
In order for an automatic label to function it has to be added to a label policy, but this, in turn, allows end users to manually select this label. This creates a gap because it is logged as an automatically labeled file/email which is to be believed that it was labeled automatically based on a ruleset.
Can you explain the impact of this scenario further?
